I purchased this as part of my job, as I sometimes run for work. Taking this opportunity, I've also gone running a few times in my private time. The size is US size 0 (XS-S). There are images of me wearing it, so please take a look. (8th image) I've worn it a few times, but there are no major scratches or stains. When I took photos of the inside of the jersey for the listing, I realized it had what looked like underwear built in! (lol) I'm a running beginner, so I'm not sure how it's supposed to be worn... (lol) But I didn't wear it directly without underwear! (See images 5-6) This is not a new item, so please refrain from purchasing if you are concerned.
